EXTE SION-TABLE.

Application filed June 14, 1920. Serial No. 388,740;

'and useful Improvements in Extension- Tables; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the charactersof reference marked thereon, which form a part of this application.

This invention relates to improvements in extension tables, and particularly over that form shown in my 'co-pending application for patent Serial No. 386,051, filed June 2nd,1920.

The principal object of the present invention is to provide an extension table, such as are used in dining rooms to normally accommodate a relatively iew people but which may be extended to take care of a considerable number, which may be extended to give a plurality of different sizes and in which the added area is had by means of permanently mounted leaves, which do not have to be removed from the table when it is desired to close or contract the table, or vice-versa.

Another object is to so arrange the exten sion features relative to the main supporting frame and legs, that the latter maintain a permanent spacing, as the frame and legs are not pulled apart as is customary with most extension tables, and which is a weak feature thereon, since the centralportion becomes a weak member when extended, there being no rigid and permanent central framework.

A further object is to provide a table of this character which may be easily set in its various positions without the necessity of lifting any weights to any marked degree, as must be done with the ordinary removable leaves. I

Another object of the invention is to produce a simple and inexpensive device, and'yet one which will be exceedingly effective for the purposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of.

the following specification andclaims.

In the drawings slmilar characters of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of thetable, closed.

Fig. 2 is a longitudinal section of the same, fully extended. Y

Specification of Letters Patent. Patented May 17 1921,

Fig. 3 is a similar section, of the table,

partly extended.

Fig. 4 is a cross section of the table. Referring now more particularly to the characters of reference on thedrawings, the

numeral 1 denotes a pair of side boards or frames, 2 transverse end frames of a lesser height than'the members 1 but terminating at the same bottom level, and 3 thesupport- 'ing legs, positioned at the junction of the side and end boards.

A central and permanent table top 4: is supported on the side boards and extends transversely thereof, these frames, legs and top forming a rigid and fixedunit,

At each end'of the top at are relatively narrow leaves 5, connected by beams 6 extending under the .top 4 and projecting somewhat beyond the ends of the leaves 5.'

The beams 6 are spacedfar enough from the corresponding side frames v1 to leave room for a pair of guide members 7 on each side and therebetween, these guides being pivoted on a common rod 8 extending be tween the boards 1.

In corresponding pairs of the guides 7 slide bars 9, extending in opposite directions beyond the leaves 5, and each such pail of bars is connected at their outer ends by transverse end boards 10. w z

A. leaf ll-is hinged to eachboard 10, as shown at 12 which, when the bars are pulled out to their fullest extent, also rest on the projecting endsof the beams 6 and are then flush with the leaves 5..

1T0 govern and limit tliemovement al-' lowed the guides 9, the underside of'the latterare notched where necessary as shown at 13 which notches engage the inner edge of the cross beams 2 of the mainframe, the guides 9 passing thereover and resting thereon. w

In order to give the leaves 5 a vertical movement equal to the thickness of the tops 4 and 11, which are of course the same, the

beams 6 rest on cams 14 eccentrically 15 to which is flexibly connected the inner its end of an operating arm 16 which projects beyond one of the end beams 2 through a slot 17 therein, the arm 16 beingnotched at a certain point as at 18 to engage the beam 2, and having a spring 19 bearing thereon to maintain the notch in engage ment with said beam, this being when the cams are moved to raise the leaves 5.

The outer end of the arm 16 is provided with a handle 20 or similar means whereby it may be grasped and pulled'by the hand. In the closed position of the table, as shown in Fig. l, the outer leaves 11 rest on the permanent center top 4 and abut against each other. In this position the intermediate leaves 5 are depressed so that the leaves 11 pass thereover in spaced relation thereto. In order to present a neat appearance, the leaves 11 are provided with e gings 21 on their under sides, which rest on the leaves 5, and abut against the top 4. Also this to 4, is provided with similar under-side e gings 22, which aline with the leaves 5 when the latter are depressed. In

this manner a stepped appearance is avoided when the table is closed up, which of course is its normal and mostly used position. If it is desired to extend the table to the position shown in Fig. 3, that is partially extended, the leaves 5. are not disturbed, and the outer leaves 11 are pulled away from each other until their ends are adjacent the ends of the top 4, when they will drop into position on the leaves 5, one set of notches in the slides 9 then engaging the end beams 2 to prevent further movement. It will be noted that the beams 9 rest at all times on the beams 2 and are also held against upward movement at their inner ends by the slides 7, while the flexible or pivoted mounting of the latter permits the raising or lowering of the leaves 11 the necessary distance without manual effort.

When it is desired to extend the table to themat the same time, since the said slides are angled relative to the plane of the various leaves.

When moved out to their limit, there is then just room for the leaves 5 between the top 4 and leaves 11, and the said leaves 5 are then raised by pulling the camoperating arm 16, which turns the cams and forces the leaves 5 up to the level of the top 4. The supporting beams 6 thereof pro --jecting beyond the ends of the leaves, said beams engage the under sides of the full limit, the slides 9 are raised from' leaves 11, and also bring them up to and hold them at the level of the leaves 5, and all parts are then in a common horizontal plane.

In this position, the beams 6 bear against the under side of the top 4, which precludes the possibility of the leaves 5 tipping at one end or theother on the cams which support them.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfils the object of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device still in practicesuch deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by tlieappended claims.

aving thus described my invention what I claim as new and useful and desire to secure by Letters Patent is 1. An extension table comprising a supporting frame, a central table top fixed thereto, intermediate leaves at the ends of the central top and normally depressed relative thereto, means for raising the intermediate leaves to the level of the central top, and outer end leaves normally overlapping the central and intermediate leaves and adapted to be pulled away from each other for certain predetermined distances.

2. An extension table comprising a supporting frame, a central table top thereto, intermediate leaves at the ends of,

thereto, intermediate leaves at the ends of the central top and normally depressed relative thereto, outer end leaves adapted to overlap the central. top and to be moved to abut against the ends of the to and also beyond the plane of the interme late leaves,

and a common hand actuated means whereby a the latter may then be raised to the level-of the top. H

4. An extension table comprising a supporting frame, a central table top fixed thereto, intermediate leaves at the ends of the central top and normally depressed relative thereto, outer end leaves adapted to overlap the central top, means whereby such leaves may be moved apart certain predetermined distances and then lay in the horizontal plane of the central member, and

means for raising the intermediate leaves to the level of the central top when the outer leaves are pulled to their l mit of movement.

5. An extension table comprising a supporting frame, a central table top fixed thereto, intermediate leaves at the ends of the central top and normally depressed relative thereto, but adapted to be raised to the level thereof at will, guide members pivotally mounted in pairs under the top transversely thereof, bars slidabl'e in corresponding guides, each pair projecting independently of the other beyond opposite ends of the top, and a leaf hinged to the outer end of each pair of slidable bars, such bars being adapted for horizontal movement to p0- sitlon the leaves carried thereby at'predetermined distances apart.

In testimony whereof I aflix my signature.
